STEERING SYSTEM
STEERING SYSTEM
Power Steering
Oil (under low pressure) provides the
power to operate the steering gear. It
also serves to lubricate moving parts
and remove heat. A loss of steering
efficiency will occur if too much heat
builds up in the system.
WARNING!
Do not operate the vehicle if the
steering system is not working prop-
erly. You could lose control of your
vehicle if the steering system is not
in good working condition, which
could result in a serious accident.
For driving safety, visually check
the steering gear and components.
Frequent checks are important for
driving safety, especially after trav-
eling over rough roads. Failure to
comply may result in death, per-
sonal injury, equipment or property
damage.
If the steering feels unbalanced from
side-to-side while turning, check for
the following possible causes:
•
unequal tire pressures
•
vehicle overloaded or unevenly
distributed load
•
wheels out of alignment
•
wheel bearings improperly
adjusted
If you cannot correct the problem,
check with an authorized dealer.
Your vehicle is equipped with integral
power steering. The system includes
an engine-driven fluid pump, a fluid
reservoir, the steering gear, and
connecting hoses. Because of the
hydraulic power assist, little effort is
required to turn the steering wheel.
When no input is applied through the
steering wheel, the steering gear will
return to the neutral position. If, for
any reason, the power assist system
goes out, steering the vehicle is still
possible, yet it will require much
greater effort.
Visually check the following parts:
